What Is Sheet Metal Fabrication? Cutting, Bending, Nesting and Job Control

Sheet metal fabrication is the process of converting flat metal sheets (steel, aluminum, stainless steel) into functional enclosures, chassis, brackets, and structural frames.

The 6 Core Operational Stages of Metal Fabrication

  • 1. CNC Laser Cutting & Turret Punching: Precision fiber laser cutting and punching of contours, louvers, and countersunk holes.
  • 2. CNC Press Brake Bending: Progressive multi-axis bending calculating bend deductions and K-factors for exact flange angles.
  • 3. Hardware Insertion & Stud Welding: Automated press-fitting of PEM nuts, threaded standoffs, and ground studs.
  • 4. Welding & Grinding: TIG, MIG, and robotic spot welding of seams followed by seamless aesthetic grinding.
  • 5. Pre-Treatment & Powder Coating: 7-tank chemical degreasing, phosphating, and electrostatic powder coating.
  • 6. Hardware Gasketing & Integration: Polyurethane foam gasket dispensing, acrylic window fitting, and lock assembly.

Key Factors in Fabrication Profitability

Profitability in sheet metal fabrication hinges directly on sheet nesting efficiency (minimizing scrap skeletons), press brake setup reduction, and accurate job-work costing that accounts for gas, powder, and machine run hours.
